100yr old Russian color photographs

A view of a long gone world, the photographs of Sergey Mikhaylovich Prokudin-Gorsky taken back around 1909 with a early color photography technique he was himself prominent in developing.

"The process used involved a camera that would take a set of three photographs. These pictures would be monochrome but each picture would be taken using a filter of a different color. When all three monochrome pictures were projected (using light which had to be specifically colored) then the original color scene could be reconstructed."
